The Qualm is a giant mass of tentacles and leaves with hundreds of mouth-like pods lined with teeth. It is about 1/8 of the size of Earth's moon, and it travels through space looking for nutrient rich planets that it can suck dry.
During a public holiday in the small town of Wyrmbersch, the Mayor is accidentally killed by a statue which falls from the roof of the Town Hall. As shocked spectators crowd around the body, they discover that the Mayor, at the moment of death, shape-shifted into a squat, stunted humanoid figure, it's grey skin dominated by bony ridges and lumps. How long was the Mayor an imposter? And who else in the town isn't what they seem to be?
